Starter issue?

Hello. I just finished a automatic to manual shift conversion on my b body.( I also own a A body). 440/727 to 833 I used a new McLeod 130t flywheel and an aluminum Lakewood bellhousing. I reused my original starter (large case stock) that had no issues before the conversion.

Now the starter sounds like a Chevy starter that needs a shim. Nasty harsh noise when the Bendix comes off of the flywheel teeth.

The nose of the starter appears to be fully seated in the recess in the bellhousing. I’m new to working on Mopars and as I understand shims are not required but something is definitely wrong. Any ideas?

Thanks as always!
